Washington (CNN) The Turkish government appeared to be regaining control of major cities Saturday the morning after a faction of the Turkish military tried to take over the country. A failed coup in Turkey — a longtime ally of the U.S. and member of NATO — could have significant and wide-ranging implications for the U.S.

That’s particularly the case, since Turkey is one of the world’s few Muslim majority democracies and it sits at a key crossroads between the West and the Middle East, with Turkey playing a critical role in the fight against ISIS in Syria, the handling of Syrian refugees and in serving as a transit point for foreign ISIS fighters.

The impact was felt almost immediately as a key asset in the U.S. anti-ISIS campaign, the Incirlik Air Base in southern Turkey just 60 miles from the Syrian border, was forced to halt operations amid the uncertainty.

As of Saturday morning, Turkish military authorities had closed the airspace around Incirlik, making it impossible for U.S. airstrike missions against ISIS from that location, Pentagon spokesman Peter Cook said in a statement.

“U.S. officials are working with the Turks to resume air operations there as soon as possible,” Cook added.

He also said the U.S. military was working to adjust its counter-ISIS operations “to minimize any effects on the campaign.”

A U.S. defense official told CNN that the Pentagon is looking to conduct operations out of other bases in the region because of the Incirlik shutdown, which the military specifically needs to operate drones to fight ISIS, also known as ISIL.

Even once the airspace is reopened, though, the U.S. military may be reluctant to restart operations until it is certain who is in control of the Turkish armed forces.

Additionally, tensions between the U.S. and Turkey could increase as an extradition battle now looms. President Recep Tayyip Erdogan has accused Fethullah Gulen, who currently lives in Pennsylvania, of being behind the coup and demanded the U.S. hand him over, though the exiled cleric has denied any involvement.

Turkish Prime Minister said that 2,839 soldiers and officers implicated in an overnight coup attempt have been arrested. At least 265 people have been killed, including 104 pro-coup participants, while 1,440 people were injured in military action in Istanbul and Ankara.

According to Prime Minister Binali Yildirim, those arrested included ordinary soldiers and high-ranking officers. He added that about 20 of those who planned the overnight coup were killed and 30 more were wounded.

Acting chief of staff of the armed forces Umit Dundar said during a press conference that more than 190 people have been killed since the attempted coup was launched.

Turkey’s government appears to have been overthrown in a coup, as the military claimed taking control over the country.

“Turkish Armed Forces have completely taken over the administration of the country to reinstate constitutional order, human rights and freedoms, the rule of law and the general security that was damaged,” the military said in a statement. “All international agreements are still valid. We hope that all of our good relationships with all countries will continue.”

The Turkish military have reportedly broken into the headquarters of state broadcaster TRT. Photos posted on social media show soldiers inside the offices.

After seizing the channel, Turkish Armed Forces broadcast a statement declaring martial law and announcing that they had“completely taken over the administration” with the aim of “reinstat[ing] constitutional order, human rights and freedoms.”

The Turkish military has taken over the government and imposed martial law, according to an announcement read by an anchor on the Turkish state broadcaster TRT. The statement was made on behalf of the “Peace in the Nation” council, the announcer said. “The political administration that has lost all legitimacy has been forced to withdraw,” the anchor said. There was no independent verification of the claim.

Some Turkish military units have attempted an uprising that will not be allowed to succeed, the country’s prime minister said late Friday in a phone interview with Turkish broadcaster A Haber.

The uprising is “an attempt against democracy and the will of the people,” Prime Minister Binali Yildirim told state news agency Anadolu. “Those who attempted this will pay the heaviest price.”

The Turkish military has issued statements, which have been published in some Turkish media, and not others, and reported by the Reuters news agency, claiming it has “fully seized control of Turkey” to maintain democratic order, that rule of law must remain a priority and international relations must remain. The statements have not been distributed through regular web channels.

There is no independent verification of either claim and it is unclear who is in charge in Turkey.

U.S. Secretary of State John Kerry told reporters in Moscow that he has been given reports about what is going on. “I don’t have any details. I hope there will be peace, stability and continuity in Turkey,” he said.

A report from the U.S. Embassy in Ankara said military-appearing jets had been flying low over the city and Istanbul for about an hour.

One tweet showed a military jet flying extremely low over the capital Ankara.

Two bridges in Istanbul are closed in one direction by the military. Cars are flowing from the European side of the city to the Asian, but soldiers and military vehicles are blocking the path to the European side.
